Fish Creek West Sanitary Trunk
The Fish Creek West Sanitary Trunk will transport sanitary flows (wastewater ) from the communities of Woodbine, Woodland, and Canyon Meadows, as well as, wastewater from Tsuut’ina Nation. This wastewater will travel through Calgary’s wastewater collection system to the Fish Creek Wastewater Treatment Plant
In response to projected growth and development in the area, hydraulic modelling, conducted in 2020, resulted in the recommendation to increase the capacity. This improvement will:
- Mitigate risk of wastewater surcharge (and subsequent property and environmental damage) due to projected increased flows;
- Support development in south-west Calgary and Tsuut’ina Nation
- And lastly, in partnership with Tsuut’ina Nation, H2S will be better managed and monitored.
Construction is expected to begin in Q2 2022 with construction completion estimated for Q4 2023.

Additional alignment information
- The sanitary pipe alignment extends 6.3 kilometers, along existing Road and Utility Rights of Way.
- This alignment was approved as it minimized impact to stakeholders:
- Do not need to cross (excavate) Canyon Meadows Golf Course
- No construction needed on Tsuut’ina lands and no crossing of Tsuut’ina Trail required
- No disruption to private property/residences
Further, to minimize traffic impact in the area, approximately 50 per cent of installation will occur on grass berm or boulevard areas.
We have secured external contractors to start the site preparation in advance of construction.
- Removing 87 trees (various species) as well as non-native shrub species (caragana) that is growing along 14th St. (between Anderson Rd and Canyon Meadows Bld.)
- We have made arrangements with the Calgary Zoo to deliver all extracted caragana bush to them. This bush will feed a variety of species, including giraffes.
- As a result of this work, Water Resources, in collaboration with Urban Forestry will replace the trees as appropriate.
Frequently asked questions
Due to current and projected growth in the area, quite simply, there will be more wastewater (sewage) than the existing infrastructure can accommodate. We need to do this work to accommodate projected wastewater flows.
No. As with all City of Calgary projects, careful consideration of the natural environment will be of utmost importance, as will adherence to all environmental standards and regulations. Alignment of this trunk has been designed to run along the existing Road and Utility Rights-of-Way, which are primarily designated for roads and/or replacing, repairing or upgrading utility infrastructure.
Removing tree is always a last resort. However, tree removal is necessary to complete this important infrastructure upgrade to your community.
In addition to tree removal, shrubbery will need to be removed. The City will replace the trees as appropriate upon project completion.
Tree compensation is based on the value of the impacted trees, which is determined by considering the health, size, species and location of the tree using standard international methods. Replacement trees are planted in the closest suitable location to replace the impacted trees.
The City works closely with our regional customers regarding water and wastewater Master Servicing Agreements.
- We continue to work with major stakeholders to ensure clear understand of the scope of work required.
- We have consulted with Tsuut’ina Nation on various matters relating to this project.
- We commit to providing timely project updates to stakeholders and citizens as we complete this important work for Calgarians.
